What to look for in a good London-based growth hacking agency?

Here are our top recommendations of what to look for in a good London growth hacking agency:

Growth marketing is a process, so you want an agency that understands the process and the culture that is required to be successful. The emphasis should be on strategy over tactics.
Be cautious of agencies that were previously more general digital marketing agencies, or that have specialisms in a particular area (such as paid advertising, or search) and that have rebranded as a growth marketing specialist in the last few years.
Ensure the growth hacking agency works with companies like yours, both in terms of customer type (B2B or B2C), and preferably industry as well. B2B and B2C growth require very different skillsets and approaches.
A good growth hacking agency will have typically used their experience to develop a bespoke growth process for new clients. Ask them about it, and avoid anyone that appears to have a "one size fits all" approach.

Which is the best growth hacking agency in London?

So the question we're often asked .... if you had to pick one, who would we choose?

This is very much an "it depends" answer but in general Kurve are a great team to work with.

Their overall approach is exactly how we think a growth hacking agency in London should operate:

Kurve is a hybrid agency & consultancy. We support on execution or strategic insight. We work on a monthly retainer or on specific projects. Rather than squeezing your brief into a fixed team, we build the team tailored to your goals. We have a broad mix of digital marketing experts. Rather than generalists, we hand-pick specialists. We use a range of robust tools, some are partners and some we’ve built for specific marketing challenges.
